java - NoSuchElement using scanner twice -
im is a working code that reads user input, so that I have a process that only the Has made, reads and returns string. . When it calls twice a process, a NoSuchElementException error which I can not do
input reader proc locate it:
read public static string () {72 scanner Leer = new scanner (System.in); 73 string entry = leer.nextLine (); 74Lear.Clos (); 75 return entry; }
How it can be used:
... system.out.println ("input value"); String padre = enter.rade (); System.out.println ("input value"); 27 string rempled = entrada.rade (); ...
Getting im
thread "exception in the" java.util.NoSuchElementException: a line found in java.util.Scanner.nextLine (unknown source modulocarga.Entrada.leerEntradaUsuario (Entrada.java:73) modulocarga.TablaSimbolica.addTaxonomica (TablaSimbolica.java:27) to (Principal.java:8) on modulocarga.Principal.main)
The first time I call it works fine, it crashes, what can it be?
Since there is only one InputStream
used its no longer possible to close input second method for reading the source
or the so-called scanner
to avoid turning off (or example a single class of scanners
application Closes at the end)
